Abstract

LOW CATEGORY CARBON DRYING METHOD. IT CONSISTS OF SUBMITTING THE COAL TO A SUPERHEATED GASEOUS MEDIA THROUGH A GENERATOR (3), THEREFORE PRACTICALLY THE CARBON MOISTURE IS SEPARATED BY DESORPTION AND SUPERHEATED GASES ARE PRODUCED FROM THE DRYING PHASE BY A DUCT (5); RECYCLE A PORTION OF SUPERHEATED GASES TO CONTACT THE COAL TO DRY AGAIN; CONTROL THE PROCESS; AND ADD ENOUGH HEAT THROUGH A REHEATER (8) TO THE RECYCLED SUPERHEATED AGENTS, SO THAT THE GASES ARE KEPT IN A SUPERHEATED CONDITION. IT HAS INDUSTRIAL APPLICATIONS TO ENRICH LIGNITE. (Machine-translation by Google Translate, not legally binding)
